17.5-inch Tall Radiator for 1964-1967 Pontiac GTO A-Body LS/LT Swap
The 1964-1967 GTO Radiator 17.5-inch tall (Manual Trans) is engineered to maintain factory hose routing and fan shroud alignment when fitting an LS or LT motor into a classic Pontiac GTO A Body. It locks into place on the original frame rails without trimming or bracket relocation by matching the original core height and port spacing exactly. Aluminum construction and a single pass design help pull heat away from high output engines and resist corrosion under stop and go traffic or spirited runs. Each unit arrives fully assembled to precise tolerances for a clean install that lets builders focus on the engine swap instead of radiator modifications.
Exact Fit for Classic 1964 to 1967 Pontiac GTO A Body Radiator Mounting
This radiator replicates the factory 17.5 inch core height and port spacing to lock into the original frame rails without any trimming or bracket relocation. Inlet and outlet ports line up precisely with stock hose diameters and bracket mounts so builders preserve OEM coolant routing and shroud alignment. The fully assembled unit arrives ready to install, saving hours of test fitting and custom bracket fabrication. By matching original dimensions, the design maintains the iconic underhood aesthetic of a mid sixties Pontiac GTO while delivering a straightforward installation experience.
Aluminum Construction Optimizing Thermal Conductivity and Light Weight
Every component is crafted from high purity aluminum to maximize heat transfer and minimize overall mass. The single pass core design channels coolant through full core height passages to avoid latent hotspots during low speed traffic or spirited driving. Because tank and core are both aluminum, galvanic corrosion is all but eliminated for longer service intervals and consistent performance. The reduced front end weight also contributes to sharper steering response and improved balance in classic A Body chassis.
Coating Options for Corrosion Protection and Underhood Appearance
Choose between a bare aluminum finish that showcases precise weld beads and machining marks or a black epoxy treatment that seals tanks and fins against moisture, salt and debris. The exposed aluminum option allows maximum thermal contact and highlights craftsmanship on restored engines. The epoxy layer adds a durable barrier to maintain a cleaner appearance under all weather conditions without compromising heat rejection. Both finishes use the same core architecture, so cooling capacity and drop in accuracy are consistent across options.
American Crafted Reliability for Quality Fit Finish and Resale Value
Manufactured in the United States under strict quality oversight, this radiator benefits from advanced welding methods and CNC machined port placement for consistent fit and finish. Local production ensures rapid quality checks at every stage, reducing the risk of dimensional variances that can plague imported units. Builders gain the assurance of proven materials and assembly practices, which translates into dependable track or street performance. A genuine made in USA unit also supports long term vehicle valuation when provenance matters to collectors and restorers alike.
